Description | Heavy, granite-derived clay soils in renosterveld, often in rocky sites. |
Threats |
| Less than 30% of this species' habitat remains intact. It has declined extensively due to habitat loss to agricultural and urban expansion, and loss continues. Most remaining subpopulations occur on small remnants, which are often degraded, and infested with unmanaged alien invasive plants. |
Population |
In spite of extensive habitat loss, this species is still very common, with recent observations indicating that it remains at at least 40 locations. It however continues to decline due to ongoing habitat loss and degradation.
